JL Audio 10TW3 -D8

Discover the 10TW3 -D8, a 10" (25cm) subwoofer from JL Audio. This subwoofer is not only one of the best-selling in the TW3 series, but also a powerful HiFi device with 400 W and Dual 8 Ohm. The 10TW3 -D8 is known for its modern construction, which is based on the core technology of JL's TW5 Thin-Line subwoofer. This offers a combination of low installation depth and high excursion. A "concentric tube" structure built into the injection-molded cone body and a low installation depth are just some of the special features of this subwoofer. The 10TW3 -D8 is precision engineered at JL Audio's factory in Miramar, Florida, and optimized for smaller enclosures.

• Building on the core technology of JL's TW5 Thin-Line subwoofers, the TW3 a powerful combination of low installation depth and high deflection. They are even able to achieve greater deflections than theW3 v3 subwoofer.
• To enable this remarkable performance, JL Audio's patented Thin-Line woofer technology compresses the architecture of the TW3 by a "Concentric Tube" structure built into the injection-molded cone body. This structure supports the voice coil and a full-ring spider while allowing the large motor structure to be placed further forward in the speaker than in conventional designs.
• The TW3 are optimized for small packages and feature JL's tab mounting design to maximize the cone area within their mounting surface. 
• Very low installation depth (3.25 / 3.50 inches)
• Very small requirements for the volume of the sealed housing
• Very long linear displacement (0.60 In / 15.2 mm, one-way linear displacement)
• DMA-optimized engine designs
• cast alloy frame
• Membrane made of injection-molded, mica-filled polypropylene
